Thanks for confirming that, Fred.  The alternative approach that
I'd probably use is to do it with an editor macro.

Actually I guess I did not communicate clearly.  I did want to modify
the output line to express the download speed two ways as
mega bits per second as well as kilo bytes per second.
The former is handy for comparison to other ways of measuring speed
that express the speed that as Mbps and communicating with /
comparison with my ISP that uses Mb/s  (Mbps).

I hope to study your code (some time) .
